In a normal year, there are a lot of factors that influence the typical seasonal demand cycle over the summer months. Yes, and some of that is driven regionally.
A lot of summer travel is tied to school calendars. Schools in the south and southeast tend to end the school year much earlier and start the new school year much earlier by mid-August. The Upper Midwest and Northeast, states like MI, OH, PA, NY, NJ, CT, etc. tend to end their school year in mid-June and restart either the week before or after Labor Day. As others have said, over the past 10-20 years they have moved up the start date increasily prior to Labor Day, and extracuriculars and school sports start their practices several weeks prior. Thus what you get is as said, there is a big push to get big family vacations in after school gets out in late-June, in July, and early August. The first or second week of August are the last big summer vacation weeks since there is a brief 1-2 week period between all the camps, summer sports leagues wrap-up, and school activities ramp-up. Not as applicable if you have elementary-school aged children, but this really factors into middle & high school student. Not to mention colleges and universities a lot start in late-August.
Typically, the busiest travel days with peak number of passengers traveling in the calendar year fall on Fridays in late-July and early-August. You have peak leisure/VFR combined with healthy business travel. Business travel declines significantly for the first 2 weeks of July around 4th of July due to everyone on holidays, vacations, but picks back up again by late-July into August.
Not to mention international, and August is peak month for inbound TATL with August being a big vacation month in Europe.
This year, who knows. September leisure travel tends to dominated in most years but the child-free, empty-nester, and senior/retiree crowd. Many of the retiree/senior crowd are too scared to fly now.
There is no sign of life of any recovery in business travel on the horizon.
